Figure 2From: Segmentation and morphological analysis of amyloid fibrils from cryo-EM image dataPreprocessed image (a) and dilated binary segmentation map (b), obtained from application of the CNN, which is then skeletonized using Zhang’s algorithm (c). Undesirable spurs (short branches) are shown in red. Pruning deletes these branches and, finally, the skeleton is split into non-branching parts (d). For visualization purposes all skeletons have been dilated by a few pixelsBack to article page
